Background: The financial implications of central nervous system (CNS) cancers are substantial, not only for the healthcare service and payers, but also for the patients who bear the brunt of direct, indirect, and intangible costs. This study sought to investigate the impact of healthcare spending on CNS cancer survival using recent US data., Methods: This study used public data from the Disease Expenditure Project 2016 and the Global Burden of Disease Study 2019. The primary outcome was the annual healthcare spending trend from 1996 and 2016 on CNS tumors adjusted for disease prevalence, alongside morbidity and mortality. Secondary outcomes included drivers of change in healthcare expenditures for CNS cancers. Subgroup analysis was performed stratified by age group, expenditure type, and care type provided., Results: There was a significant increase in total healthcare spending on CNS cancers from $2.72 billion (95% CI: $2.47B to $2.97B) in 1996 to $6.85 billion (95% CI: $5.98B to $7.57B) in 2016. Despite the spending increase, the mortality rate per 100 000 people increased, with 5.30 ± 0.47 in 1996 and 7.02 ± 0.47 in 2016, with an average of 5.78 ± 0.47 deaths per 100 000 over the period. The subgroups with the highest expenditure included patients aged 45 to 64, those with private insurance, and those receiving inpatient care., Conclusions: This study highlights a significant rise in healthcare costs for CNS cancers without corresponding improvements in mortality rate, indicating a mismatch of healthcare spending, contemporary advances, and patient outcomes as it relates to mortality., Competing Interests: The authors declare no conflict of interest., (© The Author(s) 2024.

Objectives: Long-term data on patient survivors after extracorporeal membrane oxygenation (ECMO) support remains limited. This study sought to examine the 5-year survival and health-related quality of life (HRQoL) of patients treated with venoarterial (VA)- or venovenous (VV)-ECMO., Methods: A single-center retrospective chart review and survival analysis was conducted on all patients who required ECMO from December 2007 to June 2019. Cross-sectional HRQoL assessments were performed using 8 standardized questionnaires among survivors., Results: Records for 370 ECMO patients (288 VA-ECMO, 82 VV-ECMO) were reviewed. Survival at 5 years was 33% (VA-ECMO) and 36% (VV-ECMO). Among patients that survived to 30 days, 5-year survival rates were 73% (VA-ECMO) and 71% (VV-ECMO). Sixty surviving patients (56%) had HRQoL assessments (48 VA-ECMO, 12 VV-ECMO). Median follow-up time was 4.2 (VA-ECMO) and 5.7 years (VV-ECMO). Fourteen (29%) VA-ECMO patients and 9 (75%) VV-ECMO patients reported difficulty with any activity of daily living whereas 13 (27%) VA-ECMO patients and 8 (67%) VV-ECMO patients reported difficulty with any instrumental activity of daily living. Eleven (23%) VA-ECMO patients and 7 (58%) VV-ECMO patients reported a high post-traumatic stress disorder score. Low decision regret scores in both cohorts indicated minimal regret that ECMO was initiated., Conclusions: Five-year clinical and patient-centered outcomes of patients requiring ECMO support is acceptable in those who survived the initial 30 days. Among ECMO survivors, persistent HRQoL concerns were apparent, highlighting the importance of longer-term postdischarge follow-up., (Copyright © 2022 The American Association for Thoracic Surgery.

Hypertonic saline (HTS) is a commonly administered agent for intracranial pressure (ICP) control in traumatic brain injury (TBI). The literature on its use is mainly in moderate/severe TBI where invasive ICP monitoring is present. The role of HTS in patients with moderate TBI (mTBI) outside of the intensive care unit (ICU) setting remains unclear. The goal of this scoping review was to provide an overview of the available literature on HTS administration in patients with mTBI without ICP monitoring, assessing its impact on outcome and transitions in care. We performed a scoping systematic review of the literature of MEDLINE, Embase, Scopus, BIOSIS, and the Cochrane Databases from inception to July 31, 2020. We searched for those published articles documenting the administration of HTS in patients with mTBI with recorded functional outcome or transitions in hospital care. A two-step review process was conducted in accordance with methodology outlined in the Cochrane Handbook for Systematic Reviews of Interventions . There were many studies with combined moderate/severe TBI populations. However, most failed to document subgroup analysis for patients with mTBI. Our search strategy identified only one study that documented the administration of HTS in mTBI in which subgroup analysis for mTBI and outcomes were provided. This retrospective cohort study assessed patients with mTBI who did/did not receive prophylactic HTS, finding that those not receiving HTS demonstrated a deterioration in Glasgow Coma Scale (GCS) score in the first 48 h. However, the HTS group did demonstrate a trend to longer hospital stay and pneumonia. Our scoping review identified a significant gap in knowledge surrounding the use of HTS for patients with mTBI without invasive ICP monitoring. The limited identified literature suggests prophylactic administration prevents clinical deterioration, although this is based on a single study with data available for mTBI sub-analysis. Further studies on HTS in non-monitored patients with mTBI are required., Competing Interests: No competing financial interests exist., (© Heather Rossong et al., 2020; Published by Mary Ann Liebert, Inc.)

Low permeability across the outer membrane is a major reason why most antibiotics are ineffective against Gram-negative bacteria. Agents that permeabilize the outer membrane are typically toxic at their effective concentrations. Here, we report the development of a broad-spectrum homodimeric tobramycin adjuvant that is nontoxic and more potent than the gold standard permeabilizing agent, polymyxin B nonapeptide. In pilot studies, the adjuvant confers potent bactericidal activity on novobiocin against Gram-negative bacteria, including carbapenem-resistant and colistin-resistant strains bearing plasmid-borne mcr- 1 genes. Resistance development to the combination was significantly reduced, relative to novobiocin alone, and there was no induction of cross-resistance to other antibiotics, including the gyrase-acting fluoroquinolones. Tobramycin homodimer may allow the use of lower doses of novobiocin, overcoming its twin problem of efficacy and toxicity.
